BUTTON.

SPECIFICATION forming part of Letters Patent No. 380,678, dated April10, 1888.

Application filed September 3, 1887. Serial No. 248,745. (No model.)

from a single piece of wire; and Fig. 3 is a planview showing the barsin position.

My invention relates to a class of cheap buttons which are mostly usedon pantaloons,

though they are otherwise used-as, for example, in upholstery. Thisclass of buttons are I made of thin sheet'metal disks with central iopenings and with wire bars across the open ings, whereby they arestitched to garments. The bars have been made in various forms. Straightwire bars across the openings have been used; also wire bars the ends ofwhich have been bent in opposite directions, both styles of bars formingbuttons with two holes, and with no means for holding the thread withwhich the buttons are stitched to the garment in the center of theopenings. Bars have also been made'of a single piece of wire bent in theform of the figure 8, the crossing of the bent wire being in the centerof the opening, forming buttons with four holes not all alike. Blankscut from woven wire which has been tinned or coated with an alloy bydipping the whereby the intersections of the woven wire are solderedtogether, have been used, the

blanks being so arranged that an intersection of the woven wire will bein the center of the 0 opening in the button,thus forming buttons withfour equal holes, but with sharp knife like edges formed by the coolingof the melted metal at the intersections of the woven wire as it iswithdrawn from the dip ortmelted metal, which cuts the thread as readilyas a knife.

The object of my invention is to make this kind of button with a singlepiece of wire to form with the central opening four equal holes in thebutton, and in such a manner that the thread will be held by theintersections of the wire in the center of the opening and be in contactwith smooth metal surfaces.

woven wirein melted tin or in a melted alloy,

To this end the invention consists in a piece of wire the end parts ofwhich cross each other at right angles and equal in length the diameterof a circle of which the central part is an are, as is hereinafter morefully explained.

Thefront and back parts, a and b, of the button are punched from thinsheet metal in the usual way, with central openings. The rims and formof the parts are also made in the usual and weltknown way. The straightbars 121. and or, made from a single piece of wire, Fig. 2, the endparts of which cross each other at right angles, the central part ofwhich is curved to fit within the circular rim of the back part, b, ofthe button, are placed in the back part, as shown in Fig. 3. The wire isbent or wound around a former, the end parts, m and a, equaling inlength the diameter of a circle of which the curved part a; is an arc.Then by dies the front part is closed over the back part, with the barsbetween the parts. By this construction the ends of the bars will beequidistant from each other, their intersection will be in the center ofthe central openings, and a button with four equal holes and smooth wirebars, which will not cut the thread, is the result.

Coated woven wire is much more expensive than wire, and blanks cut fromit are attended with waste. In wire cross-bars wound around a formerthere is no waste, and a cheaper and better button is the result.

Having described myimproved button, what I claim as new, and desire tosecure by Letters Patent, is-

The herein-described button, consisting of the front and back parts,combined with the straight bars at and n in one piece with the curvedpart or, the length of the bars equaling the diameter of a circle ofwhich the curved partacis an arc, the said bars arranged between thefront and back parts of the button, and crossing each other at rightangles at. the center of the openingsin said parts, as shown anddescribed.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES M. ELLIS.
